WIND'SHIELD PIVOT MOUNTING.

w ll! No. 1,449,055, dated March 20, 1923, Serial No. 449,800, filed March 5, 1921.

To all whom it may concern.

.4 .Be it known that I, ALBERT T. POTTER, citizen of the United States, residin at troit, in the county of Wayne and S tate of Michigan, have invented certain new and useful Improvements in Windshield Pivot Mountings, of which the following is a specification.

This invention relates to windshield pivot mountings, one of the essential objects being to provi el'a windshield pivot having a sectional bearing that is mounted looselv in a supporting standard and is capable of being moved transversely of the standard.

Another object 1s to rovide a clampin element that is adjustable in the standar independentlyof the bearing and is adapted to bear against an end portion of one bearing Section to move the section against the pivot member whereby the opposite end portion of the said section will be forced against a wall of the opening and the other section will be forced against the opposite wall of the opening to cause the pivot member to be clamped nonrotatively between said sections.

A preferred embodiment of the invention is herein described and is illustrated in the accompanying drawing wherein Figure 1 is a view in rear elevation of a side (portion of a windshield and the correspon ing supporting standard;

Figure 2 is a perspective view showing the bearing parts disassembled;

Figure 3 is a fragmentary side view of the bearing portion of the standard;

.Figure 4 is a vertical sectional view of the same, taken on line 4-4 of Figure 3;

Figure .5 is a vertical section on line 5-5 of Figure 4.

V In these views the reference characters A A respectively designate the ulppger and lgxiiver sections of a windshield, a indicates one of the uprights or standards u on I said sections are mounted. aid sti ndardjis formed with an enlargement C tgaccommodate a ivot bearing for the sec- $1911, A, a rectangu 'ar slot D being formed in saidenlargement. Within said slot there ishadjustablby mountiad a two-part lgearinlg 'se -00 ementary mem ers 3 5 21,? the sides fwhich are jointly conbeveled as indicated at F. Said bearing is b an annularly grooved the walls G of the groove Application for Serial No. 898,269.

of said member being beveled to correspond to the bevel F of the bearing members E and E. The pivot member G is formed with a slotted head H which embraces the frame I of the windshield section A, anda screw J is passed freely through the said pivot memher and is threaded into the frame of the windshield section to retain the latter engaged in said slot. K is a clamping screw threaded into the enlargement .C of the standard B, and having a wing head Kby which said screw may be adjPustedto press the bearing members E and i together so as to clamp the same upon the pivot member, wedging their beveled portions into the groove of said pivot member. The construc- 7 tion is such that the clamping stress is applied entirely between the beveled faces of the bearing members and the corresponding beveled faces of the pivot member. Furthermore, the construction is one that dis 7 tributes the clamping stress equally between the opposed beveled faces of the bearing, members, and over the entire area of said faces, so that a maximum frictional resistance to movement is created. The screw 00 K, as is best seen in Figure 3, bears upon the member E above the axis of the pivot bearing so as to derive a leverage in exerting the clamping stress. Also said screw is preferably arranged at a slight upward in- 86 clination so that it may be more conveniently manipulated by the driver of a motor vehicle; In addition to maintaining the pivot member G clamped between the complementary bearing members E and E, so

tablishment of a weather seal between the 96 cover edge of the section A and the cow] or dash L. I

It is preferred to interpose between the clamping screw K and the bearing members E, E a non-rotative thrust member M hav- 100 ing its end faces relatively inclined to give a maximum bearing surface between said ends and the screw K and member E respectively. A pin N is engaged in a slot 0 of said thrust member to hold'the same against rotation without preventing, transmission of the clamping stress.

From the foregoing description it will be between stame s so .I

read' n t e tional bearing is m gnx fiodel y in llie li pening (ir and that the screw K ma be adjusted in the standard independen y of the sectional bearing. oreover, the pivot member G serves as a fulcrum for the bearing section E. In use, when force is applie by the screw K to the upper end ortlon of the section E, the latter will ulcrum upon the pivot G until the lower end ortion of the section E bears against the a jacent wall of theopening where u on the pivot may be forced against the sectlon E and the latter will in turn be forced against the opposite wall of the opening D. Thus, the pivot member will be heldnon-rotatively between the sections of the bearing and the latter will e held in adjusted pos tion in the openin l Inasmuch as the o enings D extend transversely through the standards the secbearln 7 may be adjusted in the openings transver ly of the standards as desired to nipensate for any variations in the length of the windshield disposed between fi sfl efiis 1 What I aim as m invention is:

1. In a windshiel pivot mounting, the combination with a windshield and a supporting member therefor, of a sectional bearing carried by said supporting member, a pivot member carried by said windshield and extending between the bearing sections,

a rotatable member threaded into said supporting member and adapted to abut one section of said bearing, said bearing being movable with respect to said supporting member independently of said rotatable member, and means for adjusting said r0- tatable member to force a portion of one section of said bearing against said supportin member and to force one side of the ot er section against said supportin member whereby sald ivot member will e nonrgtat-ivel clampe between both sections of said bear ng member and said sectional hearing willbe retained in adjusted osition witl raspect to sa d supporting mem er.

2. In a windshield pivot mounting, the combination with a windshield and a supporting member therefor, of a sectional support movable transversely and vertically of sa d sup rting membei' fifl h section having a conica ly beveled portion, a pivot member carried, by said windshield and extending gm 1 if???

3. In a windshield pivot mounting, the combination with a windshield anda supporting member therefor, of a sectional bearing movable transversely of said supporting member, each section of said bearing hav1ng,

of said pivot mem er to clamp sald pivot member nonrotativel said clamping means also cooperating wit the beveled portions of said pivot member to revent any accidental movement of sai sections transversely of said supporting member.

4. In a windshield pivot mounting, the combination with a windshield, and a supporting member therefor having anopening therein, ot' a sectional bearin movable in the opening transversely of said supporting member, a pivot member carried by said windshield and extending between the sections of said bearing said pivot member having portions engageable with portions of said bearing sections for reventing accidental movement of said hearing sections transversely of said supporting member, and a clamping element extending through a wall of the opening in said supporting member and engageable with one of said sections to force a portion thereof against one wall of the opening in the supporting member and to force the other section against the oppb- I site wall of the openin in the supp U member whereby portio ns of both bgarg sections will engage cooperating portions said pivot members to clamp sai pivot member non rotatively, said clampin el ment also cooperating with portions said pivot member to prevent any accidental movement of said sections in the o ping transversely of said su orting memi In testimony whereot fafiin my signittnre.
